Motphological characteristics and Localization of Tree Shrew's Thymic Nurse Cells under Electron Microscope / 昆明医科大学学报

ABSTRACT

This paper reports the observations on morphological characteristics and locations of TNC in tree shrew(Tupaia beiangeri Chinensis)under EM.It is confirmed that all the TNC in 8 newborn tree shrews locate in the cortical area of the thymus.The characteristics of its ultrastructure are similar to what have been observed in the thymic cortex of human/mouse. The desmosomes of TNC and the structure that is in contact with the capillary in the human TNC have not been observed in the tree shrew.
